Hi folks!
My very first post in this forum; and my very first skin at all:

Do you have any advises for me to improve this skin?

nice start. Maybe add some small white decals.
And improve some spots of the tire pattern.

yeah, a little part of the tire pattern is lighter than the rest and doesn't blend. Also imo it would look a LOT better without the cougar on the front.
