Experimenting around with willow charcoal to sketch a three dimensional heart

My very first acylic painting. I did it on a drawing block, huge mistake.

Introduction painting class at my art space. We were asked to only use blue to paint still life. The banana was exceptionally hard. We had to get the tone and shadows right. Overall, I think that it still needs alot of work.

A sketch of an optical illusion I am working on. It is pretty difficult as it is hand drawn. I am trying to coordinate the colours but somehow it still looks kind of weird so I am still experimenting around with this. Most likely I will paint it on a huge canvas in time to come.
