Wow, that takes me back. I grew up crafting many models, since my dad was a test and fighter pilot. The horse models (equine) were not a challenge at all, so I picked up jets. Then old single-engines. Biplanes are pretty challenging. Hmm, then some cars. Good work, girl, just keep it up!! You'll only get better.
Advice as an artist on photos---keep all that crap out of there, fit the model on a large clean backdrop that fits completely. If you want to show scale, use a ruler.
