Thanks man, this is how she wants it made
Consider starting with a primitive or a mesh
Start with a cube primitive with sufficient horz and vert cuts in order to match up with the sections in your reference model -- or more.
Start with Create Polygon Tool and then the Append Polygon Tool to create a mesh that matches the side of the helmet reference model.
Extrude with the faces grouped together in order to either draw out the mesh so that it becomes 3 dimensional, OR to take your poly cube primitive and extrude an area on top that will be the helmet head/visor area vs. face/neck cover.
Do not forget to extrude more than once! Also, each time you extrude consider using the 3 Transform tools: move, rotate, and SCALE, to change each successive groupings of extruded faces.
Be sure to go into Component Mode and move the vertices around to create the layout you are looking for -- in BOTH front and side views.
There are certain areas that will require extra detail, more lines of division. Remember you can add lines to your model at ANY TIME. Simply go and choose one of the Split, Cut or Insert Edge Loop tools so that you can add a new row or column of polygons in whatever section of your model you want.
You can move and resize parts of your helmet with Vertices, Lines/Edges, and Faces! Do it!
Don't forget you may need to delete some faces in order to create an eye opening.
You can always cut your primitive model in half to work with just the right or left side and then duplicate it at the end to finish it. Or if you started with a mesh, you can build just one half from the start.
If you do work with only half, be sure to duplicate at the end, combine the two polygons, and then go and merge all the vertices or edges along that middle seam so that it is one helmet.
When you are complete, you may want to Average Vertices to get rid of any rough geometry.
Also consider Smoothing your model at the very end.
