Batman cosplay Chest Emblem for 1989 Tim Burton Batman

this is my first 3d print model.(so be gentle haha make crits contstructive on how i can improve)
i have a background in 3d modeling but have not done much for the last 10 years. so i sure am a bit rusty..

i decided i wanted to start a cosplay for keatons 89 batman. and using an old pepakura cowl. started to cut it up to use as template for a new version. the original embem seemed to be too small, *compared to the sizing from auctions of the screen used costume. so i a new one is needed.. i had made a card one a few years ago for a gift for someone and the eva foam version i made for the cowl was as i said small.. so i thought lets go for 3d printing and brought a used Ender 3 Neo. and after a few replacement parts due to bits missing or damaged by previous owner.. this was my second print.

its 15cm x 11.5cm

i printed with 20% infill and it took 5hrs on my Ender 3 Neo and seems solid enough and light
