this is a very awesome sketch of SATAM way past cool work here mate i like it i really like how you draw Robotink it looks very very very realilc and scary such is very very awesome indeed ^_^ well theres only 2 problems i had in this picture though.
1: it looks too much detail for Sonic & Sally.
2: Robotink looks way too real..
but who cares it looks great anyways
this is by far the best sketch of Sonic SATAM i ever seen in my life it's just it looks great
