V-Core 4 hybrid back benchy sign

Hey i recently build v-core 4 hybrid and printer few parts with awesome results. Made benchy and it came out almost perfect but not the sign "stern" on the back. Any tips? Nozzle 0.4. Easy pet-g in black matte from fiberlogy. 260C and bed 90C. Speed 200mm/s accel 12k. Part cooling fan in default ratrig settings.
