/ic/ - Artwork/Critique

Alright, I want in on this overcrowded thread too. OP, frustration is normal at your stage, but what i siggest you'd do is draw a bunch of heads, hands, vases, goats etc, from reference. You can copy loomis or any photo you have around. Draw that to your best ability, then do the cardinal sin and -trace- the reference. Compare the freehand drawing with the trace, and it should be more obvious what you're missing and what you should be working on.
It's obviously easier in digital but you could also draw on paper from.a ref on the monitor, then do a trace over the monitor like a lightboard and then compare the two, overlap them and note the differences. This has helped me a lot, it really teaches you to see in a different way. But you can't just do it once. The more you do it the faster you'll improve, and soon enough you won't need the trace and can just eyeball to check for differences.
