Welcome, apoclysm. Just read through some of the postings here and you will hear a lot of people mention that they've only been doing digital art for a couple years or even less, and doing some very nice works already. Myself, I've only been working digital since early 2009, after finding IFX myself, and never worked traditionally before, so mostly sketched and did some air-brushing. ... And it's never too late, whether your 26 or 46! :) How far you get along, just depends on how much time & effort you put in to it. ... You could also peruse others galleries, threads, sketchbooks, etc. and you will get a feel for how others have come along since they started out.
