3 protein-contact clashes
3 intramolecular clashes
65% of hydrophobic surface is solvent-exposed (13/20 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.

Solvent-exposed hydrophobic surface — desolvation penalty likely
