OK, since its very difficult to translate what I want to say to the pictures, such as “holes in layers, blobs”, etc. I did a graphic for you.
I think you are almost there. But you need some tweaks before you get there. Obviously, you are printing too hot. No question there. If your prints look alot like melted plastic, then you are printing too hot. Hard to tell for sure, as photos of 3d prints always look worse than they really are. But you have obvious signs of overheating. You could try keeping that temperature and printing faster, which leaves plastic in your extruder for less time, which could help.
190 is pretty low, so it could be you are just printing too slow.
Secondly, feel free to use some supports on the top edge of the open face helment (eyebrows) and keychain fob part.
Also, measure your filament. This is key to good prints. This is step one for good prints. Measure width along a stretch of filament with calipers.
I would move away from printing the marvin until you got very good with calibration items. Print a 20mm x 20mm x 10mm cube at 100% infill until you have a really, really nice cube. 100% infill will show you where you are over extruding or underextruding. (over extruding, hump on top. Under extruding = concave or layers not filled in.)
