This two shots were done with old SMC-A 50/1,7. As PP I raised temp in lightroom and crop images. What do you think about it??

The backgrounds are the first thing I notice - beautifully rendered and coloured.
I would have loved to see the sharp details of the subjects shine through here - these would be just gorgeous macro shots.
Be careful of your focusing, particularly in #2 where the middle of the twig is in focus but the important end of the twig (subject) is not. #2 also would benefit from a more compelling (non-central) composition.
#1 is the one with the most potential, but it just doesn't make it with the soft rendition of the subject. It needed some more DoF and perhaps a little cooling down to save some of the burnt highlights. But a fine result.

I really like the first shot. I agree with assessment. A fine start.
