So I'm going to give the most objective crit I can and start with saying that I'm going to avoid judgement calls based on my taste - that's 'the brown eyes look weird and I don't like them' sort of crit, which is not a critique and more a taste thing. My taste thing as a watercolourist is to try avoiding watermarks - do your wash from top to bottom smoothly and don't mess with it once it's down, or you get watermarks. Feel free to ignore me if it's an effect you're going for.
I would recommend getting a high quality scanner or taking pictures in an environment with more diffused light. It also seems as if you're drawing very small (just based on the pen width - is that ballpoint? it's bleeding badly with the watercolour and is distracting), so if you can, try giving yourself more room to play with. Also don't be afraid to work in more backgrounds or to use a ruler.
I would also rec from a legibility point of view to use block capitals because I'm struggling to read the text.
Basically, everyone's first 50 pages are rough as hell, so I'd love to see what you're like once you've got some more pages and some more practice of the fundamentals under your belt! I can only crit what I see, and I'd love to see more of it.
