Oh man, i have to respond properly now. :v
Yes, i do use a tablet, although i'm painfully aware of the fact that it's not very obvious. My hands are fairly unsteady (hence why i don't do much sniping in video games either), and nailing the right lines is annoyingly difficult, so i have to use lots of little strokes to make up for that.
Also, re: criticism:
1) I agree, it annoys me as well. Details and textures don't click in my head yet, but i guess they won't ever if i don't try. The biggest problem is that details take a long time, and i'm not the most patient person ever.
2) I'm kind of an idiot about references, because i don't want to be dependent on them, nor do i want my own stuff to be deriative of other works. I do take references when i need to practice something (HAAAAAAAAAAAANDS), but for the most part, i like to find my own way of drawing things. I know this is a horribly inefficient approach, but it's the one i like. (notable exception: i have NO idea how to draw landscapes, and will need to study that further)
3) Fancy colour palettes, thanks! Although a bit of the same as above also applies here; i'd like to be able to pull my own colour palettes out of my arse, as opposed to seeking out ones from the internet. Then again, nothing wrong with doing colour study this way, since my understanding of colours is pretty weak. :P
You are definitely highlighting the three main weak points in my doodling, and i'm genuinely surprised that they're not highlighted more often, given how glaring they actually are. Thanks for the tips, much appreciated. c:

The fishy painting is probably one of my favourites so far, it displays the least amount of fundamental flaws (i think) out of all these things. That, and eyebrows. Sweet delicious eyebrows.
