Well the ant is blurry- the high-res version of the source should be enought to make it look good in your pic. If you plan to make it look like it moves, add a new layer on top and motion blur it. Play with it's oppacity.
Also add a clipping layer with a blue overlay, over the ant - the colors reflect on shiny surfaces, and so should the sky. Again play with oppacity.
I can see you have some skills of how shadow works since you made that spikes with their tops lightened ( so... good for you ).
I wont lie that this looks good, but i can say that it can look better. Good luck!
