Create a heartwarming Valentine's Day illustration featuring a charming pair of foxes in a romantic setting. Depict the two foxes sitting side by side, with one fox gently offering a single red rose to the other. Surround them with a soft, glowing heart- shaped aura, and place them in a serene forest clearing filled with delicate pink and red flowers. Add a whimsical touch with twinkling fairy lights hanging from the branches above, and a subtle banner with the words 'Happy Valentine's Day' elegantly written in a cursive font. Ensure the overall atmosphere is cozy and romantic, with warm, inviting colors and a sense of tranquility
