Mmhmm,not bad it seems like you got a decent sense of depth
but like everyone else said,it could use some more effects.
the first one i can understand you dont really need anymore on that one.
you acheived some good underwater welding effects
the 2nd one,def could get scraped,composition (the way stuff's layed out)
is badddd,flow is baaad,render's not blended a bit,and colors arent quite coordinating.
the 3rd one,not bad,nor great>in a simplistic style its more good then bad
it looks like you were trying for lighting and depth,which are both done decently imo.
yeah you got the person blurred>but i think of when someones pulling a gun on you
will you look at their eyes or the barrel of the gun? i would think gun,so kudos on that
you text on all of em,i suck with text so i just leave it out
but thats all your call,kiu buddy
