Alright! After a long time I got my hands on the latest version of mypaint.
I was using an older version of centos7 till now, which don't support gtk3.
Finally upgraded my os and got on to the latest version of mypaint.
Had a couple of issue with oxygen theme and got that fixed on github. Thanks to @achadwick.
I will try to post my latest works here...
Before that some of my old works done in mypaint... All of them are image studies.
Please feel free to comment.
