You're pretty good at building model car kits. I like to build model cars myself, though I didn't know you could post pictures of them here.

Oh yes you can do photography as well
Just choose the model of your liking lay the pieces out choose the colors you want use tape and tape it into a circle sticky side up and sticky side down ( sticky side down on some card board and sticky side up for you to put parts on) so nothing flys off when spray painting and spray at a reasonable distance do light sprays no heavy coating (results in runs) frog tape is best to tape areas of body to have clean line when you pull tape off and it doesn't stick to pre existing layer.take your time test fit the parts before you glue ( which I use gel ) use small tools like tweezers for small areas and don't get glue on fingers especially the clear plastic it films over and fogs ( don't know if possible to fix after it's done)

Basic tips and study the instructions

I put tape on some of my models when I want a two-tone paint job. I also take time to "test-fit" pieces before putting them together, and also put together sub-assemblies before painting them to get a uniform paint job.
