Is a drawing tablet the correct way to approach 2D art?
I have a decent chunk of experience using Blender and making general art, but I came to a realization last year that my skills were stagnant, and that I wasn't going to improve without guided instruction. I joined CGCookie with the mindset that my skills were fundamentally flawed, and that I was essentially relying on tricks and shortcuts where real skill and knowledge should take precedent. I needed to relearn the basics.
Since joining, I've gone through quite a few of the modeling flows(Intro, Modeling in Blender), and I've really enjoyed them so far. However, my real weakpoint has always been texturing. Upon reaching the exercise for Introduction to Texturing, I was thoroughly sobered by how inadequate I am in that area. I have yet to complete that exercise.
Upon seeing advice in that very same exercise, I decided to look into 2D Concept. I've peaked into the Concepting flows, but have not begun them. I imagine when I do, I'm going to have to jettison all my knowledge about the subject and restart from scratch. However, before I do, I need advice.
My question: Is a drawing tablet the correct way to approach 2D art? Is drawing with a mouse a fundamentally flawed method? Are my skills poor because I lack the correct workflow and knowledge? or is it that I was doomed from the start because I learned it using a mouse? Is it both?
Normally, I wouldn't bother asking, and just continue to avoid those flows/courses until I'm ready to bite the bullet. However, with Black Friday coming up, I thought it'd be a nice time to get a tablet. I'd like to know if it's a good investment.
Sorry for the long post... it's kind of my thing.
