IMO print looks great. I can only see stringing and some minor sagging on bridges. Fine tuning nozzle temp might fix both issues. Ill give few more tips, you might find it useful:
Stringing is more difficult with bigger nozzle, but this looks like easy to remove anyway. It can also be that filament is not dry enough. Increasing retraction distance can help a lot, but too much can cause other issues.
Did you calibrate temps? Have you done PID tuning? Printing at lower temp will help with both stringing and bridging, but if you go too low you might get underextrusion or even a clog. Better part cooling can help with both as well. Lowering speed can help with bridging and faster travel speed can reduce stringing. Decreasing flow can improve the quality and reduce strength.
Its quite easy to hit thermal limits of most common hottends with 0.8 nozzle. Its good to do a proper calibration and aim for specific speed/line width/layer height/temp. I mostly print functional parts and found 0.6 nozzle better for me since it can still use maximum capability of my hotend. This doesnt count for your print from the picture since your layer height is probably only around 0.2 mm
