Orchestrated Hip Hop

lately ive been trying to make some orchestral/symphonic stuff but ive been running into a couple of problems that gets me frustrated and makes me just quit and do something else all together and i was hoping you guys might be able to help me overcome some of my roadblocks. when i try to make songs of this style, i find that all of my melodies end up coming out sad, and i dont know why...i have a good foundation of music theory but not a "know all in depth" understanding but enough so that i can talk and hold a conversation with most while understanding whats going on, but i dont know why all my stuff comes out sounding sad...at first i thought maybe it was because my progressions just went from a higher notes to lower ones, but even when i switch it up it just doesnt do what i'd like... everyones advice to producers is to find their own style and im starting to fear that MY style is depressing sh** because it just comes naturally to me.. but i overall am looking to make tracks like these http://ift.tt/1BF5JRy

if any one has any advice as to what i can do, if theres someone out there thats good at dissecting beats that could break it down for me, or if anyone knows/can help me understand why i keep pushing out sad sounding songs any advice would be greatly appreciated
