The first one is acualy realy good, but the newest or a recent photoshop is your best bet

I am seriously extremely in love with your first one. If you could do something like that, that says Philly that would be WAY chill! The others aren't bad at all either.

The first pic is really good. Just keep practicing and following tutorials!
