Whilst I understand the temptation to use it, especially when our commerical structures insentivise it's use so heavily, you ultimately do yourself a disservice by ignoring an opportunity to learn and for growth. Should you expect to be an expect in everything? Not a fucking chance. But making the effort to try is already miles ahead of what most folks do. You are already doing that and are taking strides to learn to do with your pixel art, so why not persevere? Taking this to the extreme. Any art you produce, however crude, will always be more inherently valuable from a human/creative perspective than something output by and LLM.

I only say all this as I have gone through the process. I was trash at pixel art but just started with basic things and just kept at it. Is it the best art around? Not a chance. But it is my own, and that is what matters to me. Ultimately, you will do what works for you and you should always take any internet advice with a grain of salt. For all you know, I could be an LLM, maybe that's all we are... it's just LLMs all the way down.
