I think you really need to add details or sections and more technical they are better. Your renderings and graphics look terrific, but potential employers are searching people who can do it all and they prefer more technically inclined staff.

Hey there,

To comment on the details first:

Detailing and an understading of constructablility are important but graphics of the details are perhaps more important for most firms. They want to understand that at the very least you know the fundimentals of how to make a drawing 'pop'. This means demonstrating a basic knowlege of line weights in details/ sections / plans / elevations / assemblies as well as hatches that read well and convey the information you need to convey. If you can demonstrate basic graphic standards along with this work you would be well prepared for internship.

Your graphic work should not be underestimated. Often time interns are asked to work on presentations, schematic packages/ award submissions and be 'anamatronic arms' for deigners who are not computer savvey. Having a good skills set with quick modeling and graphic skills are a good way to get an internship. Remember though, when you start you will be asked to model and produce graphics in the style of the firm and with their standards. So your voice is secondary to your ability to produce their style and standard of work.
