Kind of messy but that means there's plenty of room to improve upon. My Bismarck is not much better either though I hadn't taken the hobby seriously enough yet then.
But kit modeling is all about the fun of building it and enjoying your work after. So if you had plenty fun building it and enjoy your finish work you're doing great.
I find kit building therapeutic. Good for the soul and mind. Next to serial killing your enemies lol
I suggest that you try to spray paint the model kit with appropriate color with model kit spray cans and practice on smaller scale models. When you get the hang of it make a major project of a big model that you really like and put in the practiced skills and commitment. You'll end up with a model worthy to be displayed in the living room for all to see. But make sure you encased it either in glass or acrylic display case.
My first serious attempt at large model:
I've since added substantial make up to her which includes soot on diesel exhausts, matting the lower hull and extensive weathering on deck(white) and hull(white-an invasion of tiny white spots really tiny white spots to mimic hull abrasion by salty water current and flow) and intense tiny white splotches band forming a sort of line along the bulge on upper upper lower hull next to the bulge free flooding vents, all to give an impression of prolong sea operation or salt abrasion with the hull from waves and vents flow(weathering done with special weathering powder mixed with water). I'm very happy with the current looks compared to the original one(above) which I think was somewhat lacking.
