Monsters Escaped Again

Hello
I am creating a bag design mockup right now and i am looking for some artworks or designs i can use for preview purposes.
I wanted to ask you if i can use this work for that.
The Mockup would look like this:

(with your design placed on the bag)
Its just to show how the mockup works, i won´t sell or print your work in any way.
Looking forward to your answer
