Another pointer on using scissors to cut precise long cuts. Don't cut until you hit the tips of the blades on the scissors. Stop cutting before getting to the end of the blads, open up the scissors and move them up into the cut again and start cutting once more. This will help eliminate the stop and start marks when cutting a long edge.
Hope that made some sense?
OK Harry .It looks a little better than all yours attempts so far.So you can use that. Do you have the self healing mat for cutting? I hope yes. But if not you will need a piece of flat glass.. Stick two pieces of the blue tape you used for masking to the mat.The mat ( glass as well) has to be dry and clean at these areas where the tape has to be stuck.. I hope the tape is enough large and the template can be on it fully. But if the tape is too narrow you have to put two pieces ( short strips) of the tape one piece a little bit on the second one. Then put the template on the tape and contour this using the black marker.
Then turn the same template up and put on the second strip of the tape.Contour it again.
Then you have to cut out the contoured shapes with the scalpel.You don't need to cut deeply into the mat but it is enough to cut the tape only.When done , unstick the masks and stick to the fuselage accordingly to the profile. Remember about symmetry as both masks of shark jaws and these eyes have to be stuck exactly at the same positions on both sides of the fuselage.
Good work Harry.That's it.But these masks are a little bit too big. The jaws corner should have been on the white but it is not there.If you have a look at the colourful scan of these jaws you will notice that the length of the jaws is finished in the middle of the air intake cowling.Also the tape has to be stuck to the model surface without any folds and irregularities.
I think you contoured the template with quite thick marker and then cut going outer of the outline. Sorry Pal but it has to be corrected again.
And here your pic to show you how it should have looked like.
