it's not that bad. not that good either. my suggestions are as follows: 1. color choices are nice. You have to make that green pop out more either with highlights or some other bright colors so it's not so muddy. I like the airbrush effect but go over the actual green with maybe some fluorescent green and orange. Use an opaque white first and then spray fluoresence. 2. the background needs more oomph. nice color and I like the lines. maybe more lines? 3. The eyes really need to pop more. maybe more detail with high contrast and a little shading.
I like the pose, and I like the way it looks like search lights in the background.More pop in the colors would be nice though.
That is much better...the orange really sets him off. Great way to put the constructive criticism to work!!
