Not bad
it's got potential to be badass...it just needs some minor tweaks
the lighting is tricky because of the chrome-looking background
Use curves to make the lighting pop out more, then look at the render and decide what direction the light is coming from
then use the burn tool to darken any parts that dont make sense.....if that makes sense ._.
as for depth....all you gotta do is blur the parts that look like they're farthest away...just dont over blur because that can make it lose quality
the sig is monotone...but since the render is only light blue..you have to use darker blues to make it less monotone
Or maybe even use other colors that compliment the render
as for the text...the fonts you used are pretty bad, man...using 'tron' for the "cyborg" part and 'transformer' for the "megaamine" part would've been a better choice. you can download those fonts in dafont.com btw ._.
anyways I like v.2 better
