From what I can see, this is a cool looking chop
The matte brown paint suits it and is actually very convincing
You've also made a nice backdrop change, and fitted the atmosphere right across the image, which is good to see
A couple of areas for improvement:
>There seem to be a lot ofjagged selections ( 'jaggies' ), these happen if you don't feather the selection slightly (about 0.2 - 0.3 px). The best way to do this is to use the pen tool. Not only that but you get lovely smooth curves too
>The split lines look a little be too thick, and too dark aswell - have a look at the split line tutorial in the Tutorial area
>The lighting on the chrome grille parts at the front seems a bit bright compared to the rest of the chop - try and darken them a bit
The rest looks to be very well done - I'd love to see the main donor so I could get an idea of exactly what work you've done to the chop, but for now, good work
Thank's for the comment and yes, you have right, i have some ''jaggies'' because i use polygonal lasso tool, i hope for future to switch to pen tool even if i do not know how to use it
Split lines are so dark because if i do not do that, ther do not fit with the car, different color,but i will watch tutorials because so dark is not so pretty.
The ""kidney grills'' are bright but from the donor they come even more bright, i try to darken them but not so much because from a point, apear some pixels very bright and blue and i do not know how to get them right.
