Anyone else here using Gimp? Any tips?

[Slim]

I just completed my first attempt at lowering my truck with Gimp (no longer have use of Photoshop - long story). While I wasn't expecting much I think I did better than I had anticipated.

Anyway, i'm looking for any tips that other users may have if one wants to ..... well, you know, do what we do in here! Lift, lower, change colour, swap wheels, etc.

Anyone have any input? Do's and don'ts, if you will?

Let me know. PATIA!
