First time painting...any recommendations for easier paint schemes?

So I've decided after playing for a year or two that I'm finally going to try painting my minis. I've held off because frankly I have terrible artistic and fine motor skills and I don't want to ruin my mechs.

Ive bought everything I think I need (set of Vallejo paints, primer, brushes, dry brushes, wet pallet, matte varnish, hobby knife, cutting mat, citadel painting handle...probably more) and I'm about ready to dive in.

I was thinking about trying desert camo but I'm wondering if y'all have any suggestions on what might be an easy beginner scheme for me to get my feet wet, or any other tips on painting in general for the artistically challenged like myself :)

Thanks!
