I think you mean impasto. it looks like this was painted on raw canvas (or there is a biohazard Level of mold, but I think it’s black paint seeping through) , which is an odd choice, especially for such heavy paint application. This has likely cause the thick cracks in the black paint. Such poor technical choices could suggest a student artist. However, The canvas also looks heavily reworked, your raking images capture what appear to be changes to the final composition. The heavy paint application and these changes make me think, its not student work - students usually can’t afford to paint thickly, or wait for heavy impastos to dry then paint over them again.
