M..... the colours are great but i sugest using poster colour than it will look even better and to be honest there are some proportion problem with your drawings although its not a very big deal but except the CG i have to say most of the Gundam and their pilot are looking a bit dodgy
EG shin's hand saviours face freedom's eyes..... but that is only my opinions so don need to take too seriouse abt what i said
by the way i am really picky on drawing or painting because i choose art........so sorry abt that if it offends you in any way
