To the OP:I noticed from your post, that you say you are new to DSLRs, and that you are coming from a point and shoot camera. DSLRs have a learning curve, I have seen many folks go from a P&S camera too a DSLR because they thought that the DSLR is more of a "professional" camera, so in essence it "should' automatically take better pictures.
I too am to blame a little when I moved up to a DSLR from a point and shoot, out of the box I kinda expected to be taking better pictures than my point and shoot, I even fell in the rut of comparing all my "new" DSLR shots to those I took with my P&S, and I was really disapointed.
I then realized that I needed to put all those presumptions behind me and pay no attention to those images I shot with my P&S camera, I really needed to go back to my "film" era ways and relearn photography basics and learn to also apply them to digital. Once I started to do that my images began to improve almost immediately, and it wasn't long until my images were blowing away the images from my P&S camera.
It sounds like you either need to learn photography or relearn it, take some courses, read some good photography books,(I have the Digital Photography book collection written be Scott Kelby, I highly recommend them)
Another thing I learned is post proccessing your images and now I only shoot in RAW file format, my P&S camera only put out JPEG images and the JPEG engine in that little camera aint too bad, it does a really good job, in fact I still use that little camera, it STILL has it's place among my camera equipment/gear.
I suggest you not get rid of your DSLR, I am sure it is working just fine, you just need to learn how to use it and make it do what YOU want it to do. There is nothing wrong with the kit lens, in fact I have put out some nice shots with the same kit lens you have, however you learn the importance of quality glass as you polish up your photography skilz.
I can put out some awesome images with my K-x just as easily as I do with my K-5, so as you can see, there really is no difference in the model/brand of camera, the difference comes with EDUCATION, there is a treasure trove of free information out there in the internet. I have found a wealth of information st this site-
Digital Photography Tips: Digital Photography School and it has not cost me a dime, they have an excellent forum and lots of awesome articles on photography.
My wife is learning photography and wanted to learn on her own without me showing her, so she ordered from these folks-
On Target Photo Training - On Target Photo Training I think it cost us around $200 for this course but I highly recommend it, (disclaimer-I am in no way obligated or paid to advertize for these folks and there product, I am however impressed at the training material and have learned a lot from it)
I am not trying to dissuade you or belittle you in any way, I just want you to know that you may have to start out with the basics when it comes to a DSLR, especially when you are used to a point and shoot camera, I suggest you put your P&S away, stop comparing your DSLR shots to your P&S shots, in fact just do yourself a favor-stop looking at your P&S shots altogether, that's what I did and once I finally got comfortable with my DSLR and did a lot of practice, I went back and looked at my P&S shots and was totally blown away at the difference my DSLR makes, and that is all due to perseverance and educating myself, ya I still have a long way to go but I am now to a point where I rarely use my P&S camera, I just love the control I have over my DSLR.
I wish you luck and I hope you get the shots you want, until then I will be looking forward to your shots posted in here. Hope this post helps.
