Hiya!! Sorry for the delayed response but yes, you can draw a comic as a zine piece! We will be accepting small numbers of comic related work for the zine. In regards to specs, we'd request that there should be colour and rendering unless you want to do a black and white piece/your lineart can stand alone. However, we understand this is dependent on style so this can be discussed with the mod team upon acceptance! We hope this answers your question!
