So I've been noticing lately that my artwork, if you look closely at it, isn't particularly refined. You can still see sketch lines looking through, the brush strokes aren't laid down properly and etc.

Now I'm not a man who blames his tools instead of his skill, and certainly I'm not one to think that you can't create cool digital art unless you own a Wacom Cintiq and a cool RGB Cherry MX Brown keyboard.

However!

My drawing tablet is Trust Flex that I bought for 20 bucks and it's a really, really small tablet. Because of that I start to wonder if I simply have way too low input resolution on it. From my understanding it's the amount of points that detect the touch of your pen. Good expensive tablets I presume have a high number of such points, hence ability to lay down brush strokes with excellent precision. But cheap ones I suspect have very low number of such points, and because of that you just can't be precise. And you can't be zooming in because then you'd have to be constantly doing that and it'd be very slow and tedious. And I'm already quite slow with my art.

Google doesn't seem to have any information on this issue, since I suspect everyone goes already for a tablet at $100 or higher. Does anyone know if I'm right or it really is just me not having yet learned how to refine art? I mean I can put down okay anatomy and lighting and proportions and so on so I wouldn't think I cannot simply refine it but still...
