HMM for me I usually only feel like drawing if I have a clear idea in mind (which is bad and also why I always suffer during con season), and most of the time I DON”T actually have any solid ideas to draw? when I don’t, I just doodle faces and stuff or like fashion outfits bc those are things I draw a lot but I love drawing them anyway. LOOKING AT FASHION STUFF always inspires me though, or photographs of people/places, I like looking at that sort of thing. Also it helps a lot i think, to have a clear picture of the end product, because it’s a lot more motivating for me when I know what I’m heading towards! I’ve recently tried doing more preliminary sketches + thumbnails and stuff before drawing.
Try to let your older art motivate you maybe? If you don’t like what you see, identify what you don’t like about it and try to do it better in the next piece. Inspiration comes and goes, so don’t let it control your art! Draw even when you don’t feel inspired bc it will help boost up your art for when you actually have neat ideas to execute!
