Oh my... Look at the pure contrast. The highlights are placed on just the right spots to bring out this character's form, especially on that shoulder. You shouldn't try to improve so fast..... Keep this up, I love anything mechanical-like and this has that vibe.
The shape harmony is also very strong. Plenty of curved planes that end in slanted lines, that's development of style and character.
Boy do I feel obsolete. >__<
Aw, well I spent two months filled with 9 hour sessions,
honing my digital skill. I need more practice though.
That's freaking awesome!!! ^-^
