Hi, I'm a digital artist from Portugal!
This is actually the perfect project for me, so much so that I subbed to a membership just to apply. I started as an artist because of mtg, had the pleasure to do some workshops at wotc a few times in the past and did a few card game freelance projects in the past, including for applibot.
The rate is kind of low for what you're asking, you have to acknowledge that the artist will be doing the job of 5+ artists at the same time, including concept, art director, illustrator, UI designer, 3d modeller, rigger, animator, fx artist, among others. But for someone like me that's breaking in the industry at the moment it's fine, I can also do each of those jobs..
Regarding time, I'm available 24/7 and can adapt to any time of the day, so there won't be an issue on that regard. Please have a look at my portefolio as I have uploaded a few pieces that show a good use of fundamentals.
I also have an instagram @robinvieart and an artstation. I work in 3d as well ( I can use blender/maya/3dsmax/zbrush along with some rendering tools for both organic and hardsurface modeling), but I specialize in Unreal workflows and have next to no experience with unity at the moment. My preference is to work in 2D at the moment.
Thanks in advance and good luck with your project!
