No offense taken. Nice reference......but not like i want to make a pen artist profession out of it  .

that is really good

reallly good.
love the detail.
cant say much because this is not the end result.

I hope u can put more definition on the armor.

some shine maybe.

I like it
My opinion, you could add some detail in the environment at the back. Seems to me they are fighting in a sandy place most probably a desert. Maybe add some pyramids?
Or camels....?

Very nice! Love the dynamic feel of the illustration.

If I may critique... The shadows on the foreground character is a LITTLE too harsh for a character that's fighting in an environment like a desert, where the sand particles are actually very light-reflective, especially since it looks like the metal of the foreground mecha is light-coloured/white (?). You may also want to warm the highlights, make them more yellow-toned instead of the neutral-to-cool temperature they have right now. It'll make the heat of the desert environment more convincing

add more elements..mayb some flying dust in perspective? to create more depth of field..now it looks kinda flat..also if it has blue glow on his hand, his metallic body shouldnt look fully grey..and add more kick light to make the whole metallic surface more reflective and sharp.
just my 2cents =))
