I take a stab;

*Antifreeze tank "appears" mounted too low
*Fluid not filled to correct level
*Leaking RWP face plate gasket
*Leaking water seal on RWP
*Alternator adjustment arm on backwards
*Crimp fitting on non-factory temp T not heat shrunk
*Zip tie holding coolant hose is plastic (could melt)
*Poor routing of coolant hose around alternator
*Hose clamp too long
*Ground wire under alt adjustment not ideal location
*Aftermarket oil filter (larger OD) impinging on factory alternator bracket
*Alternator bracket had not been updated despite the timing gear case obviously having been replaced.
* Positive 12V wires not properly secured appears to be rubbing on the manifold
*Non-factory tee added to t-stat housing which can lead to improper flow around temp sender/alarm. Should be removed and plumbed correctly.
*Fuel hose on left should be better secured so as not to chafe on RWP
*White 12V wires on left appear to be chafing on fuel bleeder screw & air filter
*FWP, based on corrosion, appears to leak or has leaked
*PCV hose impinged and possibly pinched closed by alternator bracket
*Plastic zip ties in engine spaces are ABYC non-preferred.
*90 degree elbow on RWP can be a debris catcher and can increase head pressure
*Fuel hoses should be double clamped (does not look it but hard to tell)

Sorry I got more than 7 though some are hard to tell from the angle....
