Hiya! I'm Mahaugher and I guess I should write something here...
I used to use Inkscape to make my vectors, but now I'm shifting towards Ponyscape which is a derivative of Inkscape. If you are an Inkscape user and want to check it out, go here: ponyscape-vectors.deviantart.c… . It has a lot of really nice features including power-strokes and a lot of other fun things to make vectoring just a tiny bit easier.
I used to vector resources for anyone to use and as I was learning how to pony I moved on to sketches. However, these days I'm trying to push out completely original vectors with a unique style I have been working with.
Last few things I wanted to say here is that almost everything I make is free to use non-commercially. You are free to use it anywhere you want, all that I ask is for a little bit of credit and more importantly I would love to see how you use it. To the people who help share my work across tumblr, personal blogs and what have you I can't thank you enough! Every time I see it pop up somewhere I'm very, very thankful!
Recently I have had a few people ask me if I take requests. The answer is maybe is the simplest way I can put it. If you want me to make something with canon characters in a certain style doing something or other I will gladly do it but if it's an OC or something I will probably decline. It's nothing personal; Vectoring from scratch just takes forever and I'm not a huge OC kind of person. Sorry to disappoint anyone
