I've never used gouache myself o: what's it like, exactly? Consistency wise and using it and all that good stuff?
I almost thought they were watercolor for a minute there, though they were a little too opaque for that.
But, yeah. Anyways! The paintings. Tree houses are a soft spot of mine - I just adore them to pieces - so seeing these made me excited. I really like the subtle differences, besides the color schemes, that really bring alive each of the two and make all the difference in the mood o3o It's interesting to see them side by side and compare how they are so the same, yet feel so different.
