Art Swap - tool for artists

I have been working on a side project from one month and now it is ready to launch in early beta version.

I am a programmer and an artist as well. I am new to art world so it is hard for me to get followers in early stage.
I was watching a YouTube video of an artist and she was talking about art trade and I have seen that many artists are doing this so I thought it will be very helpful if there is a platform specially made for art trading to help artists.
This tool will help artists to find other artists who are willing to do art trade. It will make easy for them to reach out more people.
Please have a look!
