Absolute Beginner needing some help 😊

Hi, I have just started to use Adobe Animate and am struggling to bring in a PSD file and then use the Asset Warp tool to select the drawing I have done. I can either get the tool to select the whole page or it comes up with a error message saying that it's limiting the file to 1500 pixels and then closes the file down. The drawing is a one layer with no back ground as such although when it brings the file in, it brings in a Vector layer and a background layer. I am using Adobe Fresco to the do the drawing. Look forward to hearing back from someone. 🙂

Thanks
Carl
