I love the typefaces used in the subtime, they complement eachother quite good. Even the handwriting fits with the type. The background colour does feel blank, but i like the simplicity. The addiction of the pen im not quite sure of tho.
The splatter, and painted style on the main type seems quite good, altough im not certain the red colourchoice. The is quite saturated in comparison to the green / yellow. It fits but i would try out some other options.
Your logo seems rather not in the style of the piece. It doesnt fit in there. Overall opinion: great piece!
