That's one neat butterfly ...with wings that look like leaves....i agree that more room at the top is needed. Nicely sharp with clean background. I like it!
Besides the canvas I think you need softer light. For macro since we are going for little detail intensity, direction and quality of light is key !!
Might try a diffuser and small reflector for covering darker areas. Fun to use and will allow you to shoot at any time !! About all you won't be able to do is shoot with wind !!
I like how you got the bug parallel to the film plane, lots of detail and exposure right on!!!
Thank you for the feedback guys. I have never used flash (I do not even have a flash gun) - maybe if I did a bit more macro type work I would get one. I take on board about the harsh light.
