First and foremost, I think you'll have better luck on your art if you have a basis to go by. For example, I can't tell what your Fakémon are based off of, at all. Fakémon and Pokémon alike are based off of some kind of object; be it a living creature or inanimate object. Try giving your ideas some sort of solid basis and you might have better luck sketching your ideas out! Also, I do NOT recommend doing any sort of art in pen UNLESS you're sure about the design. Not only does pen smudge, you have to use white out to correct any mistakes unless you have one of those erasable pens. I would just use a simple #2 pencil or a led pencil with a Pink Eraser™. That eraser is amazing if you make as many mistakes as I do when I try to draw.
Your art, on the other hand is another problem in itself.
It could use some work... a lot of work, actually. Don't get me wrong, you're probably young and there is always room for improvement! Like I said before, give your Fakémon a basis to go by and then draw them out. Once you have that done, then try and develop them to the point they actually look like Fakémon. If you're having trouble with the design, you can always use the official Pokémon as references. If necessary, you can always look at other Fakémon for inspiration as well; just make sure that your inspiration isn’t plagiarizing another person. That won’t end well, trust me. I also would recommend using geometric shapes to help better your anatomy. That is an area you clearly need to improvise in.... be that as it may, you have the room to improve! Just keep practicing and I'm sure you'll be as good as Ken Sugimori one day, if not better!
They're pretty rough and plain sketches but so far so good. Add color, shading, linework, etc. to it to make it look like what it should be. Like #2 for example (I'm sorry not to be rude but I can't read your handwriting) Like if you add color, maybe you could make it look like a log using brown. Anyways, it does need some work but give it time, a base (like what it should be) and eventually those will turn into amazing fakemon. Just Rule #1, never quit, no matter what anybody says.
