Sorry for your losses man.

I think there's potential here dude, maybe black and grey realism is what you're interested in. Maybe spend more time on one piece and really go for a photo realistic piece, shade inch by inch constantly looking at your reference and smoothen out your shades.
When you're building a portfolio 5 amazing illustrations trump 10 or 15 good ones.

You're definitely going in the right direction though, just work, work, work and see the progress.

Happy drawing.
