Hello there and thank you for contacting me! I'm currently trying to get some more samples for different commissions, they will be up soon I just have a baby and am a bit slower with putting out content. Those on DeviantArt will be mostly writers oriented because I really want to engage with that community, I don't feel like people do that often enough.
As for collabs and requests, the collabs are an idea for the future that I haven't fleshed out that well but I really want to do something like that with different types of content creators including writers. I'm going to add a link bellow to a blog post I did for the requests too, it's more oriented in cartoon portraits for now and will be happening less regularly, but it will be a thing that I'm hoping to keep constantly going over time. It looks like a pretty long post since I do work with people often and am used to giving all the information I can in advance, hopefully it clears up things as much as possible:simplydikka.com/2017/01/simply…
You can always note or email me with any other questions, I will most likely be more quick to reply in an email since I do check those on the daily, but I'm doing my best to be on top of all DA related too.
